BARNSTABLE, Mass. (AP) — A Plymouth woman who posted a photo of herself pantomiming a yell and making an obscene gesture at the Tomb of the Unknown Soldier has been placed on unpaid leave from her job at a Cape Cod home for the disabled.

LIFE, Inc. said they are investigating the incident involving Lindsey Stone and a co-worker who took the photo. The chief financial officer told the Cape Cod Times Tuesday that the Hyannis nonprofit is "appalled."

Stone was on a company-sponsored trip to Arlington National Cemetery last month when she posed by a sign reading: "Arlington National Cemetery: Silence and Respect."

Stone posted the photo to Facebook and it went viral. A Facebook page called "Fire Lindsey Stone" has since been created.

Stone's listing couldn't be found Tuesday and she couldn't be reached for comment.
